### Generating Application Metrics
Application metrics are generated and exposed via an event emitter interface. Whenever a request has been processed and it about to be returned to the customer, a `data` event will be emitted:
```javascript
jsonApi.metrics.on("data", function(data) {
// send data to your metrics stack
});
```
This is the data made available via this interface:
```javascript
{
route: "people/:id/parent",
verb: "GET",
httpCode: 200,
error: "Optional error message",
duration: 123
}
```
